However KBS planned it as a film from the beginning. Broadcast content is difficult to show in Japan, but for film, it is easier to go to film festivals or screen them. It could at least be screened at human rights film festivals. So, from the beginning, they formed a broadcasting staff and a film staff together, and the scenario was also written in collaboration with the film staff. It all started with the hope that more people would watch the movie and learn more about this issue.^[8][13] The theatrical cut was first showcased at the 16th Jeonju International Film Festival.^[11][12] The film version was finally released in theater nationwide on March 1, 2017,^[8][13] also known as the Independence Movement Day in South Korea, which commemorates the 1919 March 1st Movement.^[14] In 2016, Snowy Road won the Prix Italia Award in the TV Drama/TV Movie category at the 67th Prix Italia Award Awards.^[15]

We put a lot of effort into expressing the luxury of the real upper class on screen. Because it is set in the top 1%, I thought there should be plenty to see, but the visuals should not be boring or distracting. I wanted to create a drama that would appeal to viewers’ eyes and ears. We created a visual pre-production team (prior to filming) and prepared the concept for about 4 months, researching what kind of buildings the upper class likes in 2021 and what they use, wear, and eat. Based on this, we clearly communicated the image and direction we wanted to create to the staff, including the cinematographer and art director, and completed the work together. I also wanted to present a new standard for luxury. I tried to convey the feelings of real rich people by clearly choosing emptiness and filling.
